2026-04-30 Betatron X-ray Platform Driven by 200TW/1Hz Ti:sapphire Laser at SIOM doi:10.57760/sciencedb.35195 en Laser wakefield acceleration (LWFA)-driven betatron X-ray sources have advanced rapidly, yet high-performance outputs typically rely on high-power lasers or stringent optimization schemes. To expand the application capacity of the 200 TW/1 Hz Ti:sapphire laser facility at SIOM, we develop an integrated LWFA-based betatron X-ray platform, which generates 1.28 nC electron beams and hard X-rays with a critical energy of ~15 keV, reproducible photon yields above 109 photons/shot, a maximum yield of 2.12×109 photons/shot, and realizes 6 μm-resolution X-ray imaging. This work validates the source’s practical application potential and underpins the applied exploration of compact laser-plasma radiation sources. betatron X-rays; laser wakefield acceleration; hundred-terawatt laser system; X-ray imaging Wei Jianmeng Zeng Gaojie Guo Hang Wen Jiaxing Ye Hansheng Wu Sixin Fan Sijie Wang Shaoyi Zhang Hong Zheng Yinlong Peng Mao Xiangjun Zhu Tao Gong Qiang Wei Lai Shen Xianfeng Wu Yuchi Zhao Zongqing Wang Hao Wang Jia Gui Jiayan Xia Kegui Xu Yi Feng Ke Li Song Wang Wentao Leng Yuxin Li Ruxin PUBLIC https://creativecommons.org/licenses/by-nc-nd/4.0/ dataset Science Data Bank
